class Doctor(models.Model):
    user = models.OneToOneField(CustomUser, on_delete=models.CASCADE, null=True, related_name="doctor")
    image = models.ImageField(default='jazeera.jpg', upload_to='profile_pics')
    bio = models.TextField()
    speciality = models.CharField(max_length=300)
    describtion = models.CharField(max_length=100)
    status = models.ManyToManyField(Status)

Answer 1

Doctor 对象没有用户名，因此：

user = get_object_or_404(<s>Doctor</s>, username=self.kwargs.get('username'))

没有多大意义，但是你不需要先使用get_object_or_404 来获取用户，你可以过滤：

from django.shortcuts import get_object_or_404

class DoctorDetailView(LoginRequiredMixin, DetailView):
    model = Doctor
    fields = ['user', 'email', 'image', 'speciality', 'bio']
    template_name = 'pages/doctor_detail.html'

    def get_object(self):
        return get_object_or_404(Doctor, user__username=self.kwargs['username'])
